@Ajay-singh1 Thanks! But keeping the limelight on making the SEO better, apart from fixing typos and fixing translation issues, what made you add API Gateway to all the above pages? Do give a read where exactly API Gateway is being used and then update accordingly.

Once done, could you squash all commit messages into a single one?

[Ajay-singh1]

Sure!

[Neilblaze]

@Ajay-singh1 Also, before you do that, switch to the master branch, update it to upstream, create a new branch from the master, make changes, commit, and create the pull request.

Adding to the keywords list might be good, but I don't see the need to forcefully change APISIX to APISIX API Gateway everywhere.

I have rectified it.

@Ajay-singh1 I'm repeating, follow this first and then squash all commits into a single one. Make sure to perform a Sign-Off.

If you can't then lemme know, I'll cc you in a different PR which I'll open once you confirm.

[Ajay-singh1]

I don't know how to squash all the commits.I am afraid it can lead to merge conflicts.Can you redirect me to a different PR?

Thanks for your review.

[Neilblaze]

Okay, I'll do it by eod (IST).
